Window & door mastic in Woodend, Hampshire
Professional window mastic in and around Woodend, with every bit of old sealant taken out first.
- Cold air getting in at the frame edge
- Cracked internal joints between frame and plaster
- Leaking joints at the ends of sills
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
How we handle window mastic in Woodend
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. Common call-outs are for a bead that doesn’t match the frame and old mastic that has gone black or come away, on patio & French doors, timber windows & doors and composite doors.
Outdoor sealant needs dry, clean surfaces, so work on frames around Woodend is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Big or small, it’s backed by our one-year guarantee.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Keep paint off silicone joints
- Clean frames with a soft cloth and soapy water
- Make sure the drainage slots aren’t blocked
- Do not aim a pressure washer at the joints
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Woodend homes and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Botley station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you live in an older home near Church of the Holy Trinity, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Swanmore College of Technology are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- A sash or casement that will not close properly
- Draughts through the window seals rather than the frame
- Soft or decayed wood in the frame
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.

How the visit works
We keep the work tidy and contained to the area we’re working on. Expect the work to take most of a day for a typical house, less for a few frames, and we tell you how long to leave it before we go. Somewhere like Woodend needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Before we arrive
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property

Advice
Different surfaces, different methods
Patio & French doors
Water at the foot of a door frame is not always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We’ll tell you if that’s what we find.
How we quote for window mastic
Jobs vary more than people expect. What affects the quote:
- Mould in or behind the old joints
- The old material and how stubborn it is
- The number and length of the joints
- Access and height
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- Access, such as stairs, a lift or height
- Roughly how big the job is
- The type of property
- Where the job is, and your postcode

Questions from Woodend
Can you help a landlord with a rental near Botley station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Is Woodend in your area for window mastic?
Yes. We work across London and the South East, and Woodend is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can you reach windows above the ground floor?
Yes, in most cases. We plan safe access before the job, so mention the height and anything in the way.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
What happens if it’s left?
Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. If we find failed glass units or worn seals, we will tell you. Around Woodend, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
